Light therapy for older persons with dementia is often administered with light boxes, even though indoor ambient light may more comfortably support the diverse lighting needs of this population. Our objective is to investigate the influence of indoor daylight and lighting on the health of older adults with dementia living in long-term care facilities. A systematic literature search was performed within PubMed, CINAHL, PsycINFO, Web of Science and Scopus databases. The included articles (n=37) were published from 1991 to 2020. These articles researched the influence of existing and changed indoor light conditions on health and resulted in seven categories of health outcomes. Although no conclusive evidence was found to support the ability of indoor light to decrease challenging behaviors or improve circadian rhythms, findings of two studies indicate that exposure to (very) cool light of moderate intensity diminished agitation. Promising effects of indoor light were to reduce depressive symptoms and facilitate spatial orientation. Furthermore, there were indications that indoor light improved one’s quality of life. Despite interventions with dynamic lighting having yielded little evidence of its efficacy, its potential has been insufficiently researched among this study population. This review provides a clear and comprehensive description of the impact of diverse indoor light conditions on the health of older adults with dementia living in long-term care facilities. Variation was seen in terms of research methods, (the description of) light conditions, and participants’ characteristics (types and severity of dementia), thus confounding the reliability of the findings. The authors recommend further research to corroborate the beneficial effects of indoor light on depression and to clarify its role in supporting everyday activities of this population. An implication for practice in long-term care facilities is raising the awareness of the increased lighting needs of aged residents. Original article at: https://doi.org/10.2147/CIA.S297865

Posttraumatic nightmares (PTN) are a frequent symptom after a traumatic event and often play part in the psychopathology of patients with borderline personality disorder (BPD). Imagery rehearsal therapy (IRT) currently offers the best evidence for an effective treatment to reduce PTNs, although high drop‐out rates are common. Art therapy in IRT may counteract this, by its indirect, nonverbal, and often playful approach that helps to break through avoidance. This case study focusses on the perception of a patient with BPD in an art therapy based IRT treatment for patients with PTNs. It tells the story of Aurelia, a 40‐year‐old woman who, within this treatment, processes traumatic contents of her childhood like physical and sexual violence, but also current interactional problems that manifest themselves in her nightmares. Following the IR‐AT treatment for PTNs Aurelia noticed a reduction in her nightmares, was less afraid of them and felt calmer towards her trauma. She expressed herself in the art medium and by this developed more self‐efficacy. Her process resulted in an integration of the trauma and a perceived decrease in borderline symptoms. Future research can build on this basis to further explore the mechanisms and effects of IR‐AT for PTNs.

Daylight has been associated with multiple health advantages. Some of these claims are associations, hypotheses or beliefs. This review presents an overview of a scientific literature search on the proven effects of daylight exposure on human health. Studies were identified with a search strategy across two main databases. Additionally, a search was performed based on specific health effects. The results are diverse and either physiological or psychological. A rather limited statistically significant and well-documented scientific proof for the association between daylight and its potential health consequences was found. However, the search based on specific health terms made it possible to create a first subdivision of associations with daylight, leading to the first practical implementations for building design.
